Electroencephalogram (EEG), Awake and Asleep

Massachusetts rates for HCPCS 95819

Small sensors placed on the scalp record the brain's electrical activity while the patient is monitored both while awake and while asleep. This combination can reveal abnormal brain wave patterns, such as those linked to seizures, that might not show up during wakefulness alone. It is a noninvasive test that takes no direct sampling from the body.
